Abstract
A current level detector device for protecting a circuit against alternating current overcurrents includes resistor arrangements that are inserted into the circuit to be protected and two detector cells, one for each half-wave of the current. The detector cells are similar to each other and are connected to the terminals of the resistor arrangements. By means of a crossover circuit, the two detector cells are both connected to the terminals of the same resistor arrangements. Applications include protecting circuits using power semiconductors.
